Turbulent Linewidths in Protoplanetary Disks: Predictions from Numerical Simulations
Turbulent Linewidths Protoplanetary Disks: Predictions Numerical Simulations
2011/10/11
Sub-mm observations of protoplanetary disks now approach the acuity needed to measure the turbulent broadening of molecular lines. These measurements constrain disk angular momentum transport, and fur...
In previous studies, we examined turbulence-flame interactions in carbon-burning thermonuclear flames in Type Ia supernovae. In this study, we consider turbulence-flame interactions in the trailing ox...
Cross-helicity effects and turbulent transport in magnetohydrodynamic flow
Cross-helicity effects turbulent transport magnetohydrodynamic
2011/9/28
In the presence of large-scale vortical motions and/or magnetic-field strains, the turbulent cross helicity (velocity--magnetic-field correlation in fluctuations) may contribute to the turbulent elect...
The Interaction of High-Speed Turbulence with Flames: Turbulent Flame Speed
Turbulent premixed combustion, Turbulence, Flamelet, Turbulent flame speed, Hydrogen-air combustion
2011/9/14
Direct numerical simulations of the interaction of a premixed flame with driven, subsonic, homogeneous, isotropic,Kolmogorov-type turbulence in an unconfined system are used to study the mechanisms de...
High-resolution simulations of planetesimal formation in turbulent protoplanetary discs
High-resolution simulations turbulent protoplanetary discs
2011/1/10
We present high-resolution computer simulations of dust dynamics and planetesimal formation in turbulence generated by the magnetorotational instability. We show that the turbulent viscosity associate...

The statistical properties turbulent motions massive galaxy clusters
2011/1/13
We study the properties of chaotic motions in the intra cluster medium using a set of 20 galaxy clusters simulated with large dynamical range, using the Adaptive Mesh Refinement code ENZO (e.g. Norman...
The Formation of Low-Mass Binary Star Systems Via Turbulent Fragmentation
Solar and Stellar Astrophysics (astro-ph.SR)
2011/1/7
We characterize the infall rate onto protostellar systems forming in self-gravitating radiation-hydrodynamic simulations. Using two dimensionless parameters to determine disks' susceptability to gravi...
Enhanced Core Formation Rate in a Turbulent Cloud by Self-gravity
Galaxy Astrophysics (astro-ph.GA)
2011/1/5
We performed a numerical experiment designed for core formation in a self-gravitating, magnetically supercritical, supersonically turbulent, isothermal cloud. A density probability distribution functi...
Turbulent eddy-time-correlation in the solar convective zone
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/31
Theoretical modeling of the driving processes of solar-like oscillations is a powerful way of understanding the properties of the convective zones of solar-type stars. In this framework, the descripti...
